Manufacturing object 3D data generation step, manufacturing object stacking step according to 3D data, 3D scanning step of scanning the surface of the stacked manufacturing object using a 3D scanner, spraying a mixture of shotcrete and quick-setting agent on the surface of the manufacturing object according to 3D data It provides a high-quality concrete 3D printing structure manufacturing method comprising a surface processing step and a final product acquisition step. The high-quality concrete 3D printing structure produced in this way has less deformation due to continuous supply and flow and a short stabilization time, making it easy to manufacture concrete structures through 3D printing, as well as improving the quality characteristics of manufactured concrete secondary products or moldings. Satisfactory strength, durability and eco-friendly characteristics can be provided. |
